Clean Print Platform

This section assumes you have already taken steps in the Post-Processing Guide to remove the printed part from the print platform. 

CAUTION: Do not clean the print platform in a sink or tub that drains into wastewater. This component must be cleaned in a self-contained tub and the resulting solvent/resin mix must be discarded according to all local, state, and federal regulations.

WEAR 100% nitrile gloves throughout this procedure.

Clean Print Platform

You must clean the print platform after each use.

  1. Use the punch tool to punch out the bits of supporting architecture that are inside the holes. Punch in a column, going up an down until you have run the punch tool through every hole. See the punching pattern below for reference.

  1. Use the Platform Scraper to scrape cured resin off the underside of the print platform. If you are running an elastomeric material such as ELAST-BLK 10, please see the section below, Special Consideration for Elastomeric Resins.

  1. You should have the platform-cleaning fixture in a tub with IPA. Place the print platform on the fixture, being sure it is submerged in the solvent, and use the punch tool up and down on the platform once more, as you did in Step 1.

  1. Wipe down the platform with a lint-free paper towel or nonabrasive cloth.

  1. Inspect the platform, particularly the holes on the flat surface, to ensure no partially cured resin remains. If you find resin or partially cured bits on the platform at this point, follow the steps in this section again on the problem areas.
  2. Allow the platform sufficient time to dry. Use compressed air to speed up this process, if desired.

Your print platform is now clean and ready to be reused.

Special Consideration for Elastomeric Resins

For cleaning print platforms that run elastomeric resins such as ELAST-BLK 10, your printer package includes a Wire Brush accessory. The following instructions demonstrate how to use this brush.

  1. Use the Platform Scraper to remove as much partially cured resin as you can.
